Abstract: Several security threats are present in the satellite communication system now-a-days. Specially, after incorporating Route Optimization between end hosts by informing correspondent node and home agent about mobile node's current location through binding updates in Mobile IPv6, security threats have become alarming. Vulnerability of the binding updates under several attacks is the main reason of these security threats. The attacks include sending unauthorized and unnecessary data to mobile node, redirection of traffic, denial-of-service attack, man-in-the middle attack, bombing attack, etc. The effect of these attacks is severe on various sophisticated mobile nodes such as satellite, air-crafts, naval ships, drones, etc. Several approaches have been used to prevent these attacks. However, any suitable solution to all these attacks is yet to be found. For these reason, we propose a new solution to all these attacks through incorporating a notion of run-time authentication between the sophisticated mobile nodes. Our proposed solution ensures that no unauthorized agent can manipulate and send modified data packets to the mobile nodes. Consequently, our system of run-time authentication can be used in any highly-secured network system to ensure authentic data communication.
